Answer:
-2/5
-4/9
Step-by-step explanation:
-5/6 = -0.83333 (three's keep repeating)
-3/8 = -0.375
the above are both rational because they result in a repeating or terminating decimal
There are an infinite number of rational numbers between the two listed above but here are some:
-2/5 = -0.40 (terminates)
-4/9 = -0.4444444 (fours keep repeating)
-1/2 = -0.50 (terminates)
-3/4 = -0.75 (terminates)
Three consecutive integers add up to 51. What are these integers
Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+x+1+x+2=51
=>3x+3=51
=>3x+3-3=51-3
=>3x=48
=>x=16
Hence, first integer = 16,
second integer = 16 + 1 = 17 and
third integer = 16 + 2 = 18.

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what sea is in simplest radical form
Answer:
C = 18
Step-by-step explanation:
There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form
Solution:
A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.
The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).
A right angled triangle is a triangle with one angle equals to 90 degrees.
Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:
sin30 = 9 / C
0.5 = 9 / C
C = 9/0.5
C = 18
Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
cos A = 24/51
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Cos theta = adj side/ hypotenuse
cos A = 24/51
Step-by-step explanation:
We know that cosA=Base/hypontenuse
➡CosA=24/51
Reason :-This is a right angle triangle
Cos theta=Base/hypontenuse

Which of the following are the coordinates of Q? Plz I don’t want fail my sophomore year
Given:
Segment MN has endpoints at M(-6, -3) and N(9,7).
Point Q lies on MN such that MQ:QN = 3:2.
To find:
The coordinates of point Q.
Solution:
Section formula: If a point divides of line segment whose end points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in m:n, then the coordinates of that points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Segment MN has endpoints at M(-6, -3) and N(9,7) and Point Q lies on MN such that MQ:QN = 3:2. By using section formula, we get
[tex]Q=\left(\dfrac{3(9)+2(-6)}{3+2},\dfrac{3(7)+2(-3)}{3+2}\right)[/tex]
[tex]Q=\left(\dfrac{27-12}{5},\dfrac{21-6}{5}\right)[/tex]
[tex]Q=\left(\dfrac{15}{5},\dfrac{15}{5}\right)[/tex]
[tex]Q=\left(3,3\right)[/tex]
Therefore, the coordinates of point Q are (3,3).

Answer:
First, we can find the least common denominator for 8 and 3 which is 24.
5/8 = 15/24
1/3 = 8/24
Then we can divide 15/24 by 8/24 which is 2 1/4.
If we then do 16 divided by 2 1/4 we get 7 1/9
Answer = 7 1/9

What is the surface area of a cylinder with a height of 20 meters and a diameter of 10 meters? O A) 1884 m2 OB) 863 m2 OC) 353.25 m2 OD) 785 m2
Answer:
785
Step-by-step explanation:
did the math in a calculator I got yoy
Answer:
D. 785
Step-by-step explanation:
the formula to find the surface area of a cylinder is A=2πrh+2πr^2
the diameter is a straight line through the center of a figure so half of that would be the radius and our diameter is 10 so the radius is 5
our height is 20 so now we put it into the equation it will look like this
2·π·5·20+2·π·5^2
once you do the math you will get 785.39816
Find the surface area

el punto (4, -3) esta sobre el lado terminal del angulo 0 en posicion normal. hallar el valor de las seis razones trigonometricas de ese angulo
Answer:
Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:
Tan(θ) = y/x
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:
Ctg(θ) = x/y
Sec(θ) = √(x^2 + y^2)/x
Csc(θ) = √(x^2 + y^2)/y
En este caso tenemos el punto (4, -3), es decir:
x = 4
y = -3
Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:
Tan(θ) = -3/4
Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5
Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5
Ctg(θ) = 4/(-3) = -4/3
Sec(θ) = √(4^2 + (-3)^2)/4 = 5/4
Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3
graph the equation y = 2 (x - 4)^2 + 5
Answer:
Step-by-step explanation:
write the slope-intercept form of the equation of the line through the given points.
Answer:
y = 4x - 7 (Answer C)
Step-by-step explanation:
First find the slope of this line. Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.
Thus, the slope, m, is
m = rise / run = 4/1, or m = 4.
Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:
y - k = m(x - h) becomes y - 1 = 4(x - 2)
Solving for y, we get: y = 4x - 8 + 1, or y = 4x - 7 (Answer C)
Is algebra.

Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

A = {prime numbers between 4 and 25} B = {odd numbers less than 16} List the outcomes of A, B and explain? List the outcomes of A, B and explain?
The image below better explains it. Thank you.
Answer:
A u B = {1,3,5,7,9,11,13,15,17,19,23}
A n B = {5,7,11,13}
Step-by-step explanation:
The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23
A = {5, 7,11, 13, 17, 19,23}
B are odd numbers less than 16
B = {1, 3 , 5,7,9,11,13,15}
The union of both is the list of all values present in both sets without repeating;
A u B = {1, 3, 5,7,9,11,13,15,17,19,23}
A n B is the set that contains values that are present in both sets
A n B = {5,7,11 , 13}
